The surface drive propulsion system (also known as semi-submerged propeller) independently developed by Tofoo Electronics Engineering Co., Ltd. for TSD type high-speed boats has been tested in Changsha, China, with a maximum measured speed of 78.9 km/h, which has been successfully used in high-speed boats. This technology has obtained a number of utility model patents and invention patents. The success of this test voyage fully demonstrated the maturity of the key technology and core technology of the high-speed surface propeller device, marking that the surface propeller device and surface propeller technology for domestic TSD high-speed boats have gradually matured, and the application direction of the product will be more mature. It is safe, efficient and cost-effective.
Design Advantage
A pair of TDS surface drive can lift and steer system
A pair of high anti-corrosion, high toughness and
strength two-way special stainless steel surface perforated propellers
Hydraulic and steering equipment
The body i s made of all 316L anticorrosive stainless steel
Indicators and sensors
Double hydraulic cylinder
Two kinds of adjustable movable and fixed semi-submerged propeller systems
Universal ball cage connection design
Performance Advantages
The water intake of the surface piercing propeller i s half of the water intake
15% to 30% faster than traditional systems
15% to 30% increase in fuel efficiency
The propeller i s ventilated to the water surface, thereby reducing noise and destructive hull and pillar erosion.
The maintenance requirements are low, and the propeller immersion can be adjusted in progress.
